BROODER.

Application filed September To all whom it may concern.

Be it known that l, Josnrrr A. STEPHENS, a citizen of the United States, residing at Vermilion, in the county of Clay and State of South Dakota, have invented certain new and useful Improvements in Breeders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

lily invention has for its object to provide a simple and desirable brooder h ving a novel association of parts for dividing its interior into an upper warm air chamber, a cool air chamber at one side of said warm air chamber, a lamp chamber below the warm air chamber for heating the latter and a cold air chamber at one side of said lamp chamber and extending under the cool air chamber a runway from the upper chambers being extended through but partitioned from said cold air chamber.

With the foregoing in view my invention resides in the novel subject matter hereinafter described and claimed the description being supplemented by the accompanying drawings.

Figure 1 is a front elevation of a brooder constructed in accordance with my invention.

Figure 2 is a vertical transverse sectional view as indicated by line 22 of Fig. 1.

Figures 3 and a are vertical longitudinal sectional views on the planes indicated by lines 3-3 and 4-4 of Fig. 2.

In the drawings above briefly described, the numeral 1 designates a rectangular casing whose front and rear sides have been designated by the reference numerals 2 and 3 and its ends by the numerals a and 5, for future reference. The casing is provided with a suitable top which preferably consists of a rear upwardly swinging section 6 and a front similarly movable section 7, the latter having transparent panes 8 therein. Either or both of the sections 6 and 7 may be swung upwardly, for instance when feeding the chicks and when cleaning the brooder.

The casing 1 is divided horizontally by a floor 9 and the space above this floor is divided by a vertical longitudinal partition or curtain wall 10, into a warm air chamber W, and a cool air chamber C, the two chambers being in communication, as the curtain 4:, 1923. Serial No. 660,927.

wall 10 has its lower edge spaced upwardly from the floor 9. The chamber 3 is preferably provided with suitable ventilators 11. Below the floor 9, the casing is divided by a vertical longitudinal partition 12 into a lamp chamber L and a cold air chamber 0, said partitions 12 being extended entirely from the end wall 1 to the end wall 5, as is also true of the curtain wall 10. The floor 9 extends between the ends 41 and 5 and between the front and back walls 2 and 3, one corner of said floor however being provided with an opening 13 from which a stairway or other runway 1d, declines to a front door 15. To cut off communication between the cold air chamber C' and the interior of the brooder, through the opening 13, 1 have provided a vertical transverse partition 16 which is secured to the inner edge of the stairway or runway 14, passes through the opening 18, and extends a suitable distance into the cool air chamber G. l Vhile the out line of this partition 16 does not appear in full lines in Fig. 2, T have shown such outline by the dot and dash lines designated at 17.

The portion of the floor 9 at the top of the lamp chamber L, is provided with a sub floor 18 spaced downwardly from said floor 9, to provide a dead air space 19 between the two floors, which prevents overheating. Below the sub-floor 18, I have shown a pair of heat spreading plates 20 which are suspended from the sub-floor by suitable suspenders 21, and under these plates two lamps 22 have been illustrated, which are accessible through a pair of doors 23 in the rear side 3 of the casing 1. The lamp chamber is provided with suitable bottom plates 24 upon which the lamps 22 rest. Appropriate upwardly diverging heat distributing plates 25 extend transversely across the lamp chamber la, the lower edges of said plates being in spaced relation to receive the lamps 22 between them.

Air is supplied o the lamps 22, through suitable openings in the ends a and 5 and gas escape openings 2'1 are formed in the partition 12 and in the portions of the end walls l and at the ends of the cold air chamber C.

By the heating means, it will be seen that the portion of he floor 9 at the bottom of the chamber 5V, will be heated to the desired extent, to effectively heat the air in said chamber, so that the chicks may have the required amount of heat, but if they wish, they can pass under the curtain wall 10 into the cool air chamber C which receives very little heat, due to the fact that it is separated from the chamber W by the curtain wall 10 and is located above the cold air chamber C. Whenever desired, the door 15 may be opened and the chicks may pass down the runway 14: into a suitable yard or run (not shown).

VBy providing the construction shown and described or a substantial equivalent thereof, a brooder is provided which is desirable in numerous ways, and as excellent results have been obtained from the general association of parts hereinillustrated, such association is preferably followed. However, within the scope of the invention as claimed, numerous minor changes may be made.

I claim A brooder comprising a rectangular openbottomed casing, a horizontal floor dividing said casing between its upper and lower extremities, and having a transversely elonedge contacting with one end of said casing,

and a vertical transverse partition rising from the inner edge of said runway through said opening and secured against the inner side edge of the latter and to said front of the casing to make it impossible to gain access from the lower to the upper portion of the casing, a vertical, longitudinal partition extending from end to end of said casing and spaced upwardly from said floor, dividing the space above the floor into a warm air chamber and a cool air chamber, and a second longitudinal partition in the casing below the floor, dividing the space under the floor into a lamp chamber disposed under the warm air chamber, and a cold air cham ber under said cool air chamber.

In testimony whereof I have hereuntoaflixed my signature.

JOSEPH A. STEPHENS.
